PROVIDENCE, R.I. — A federal judge in Rhode Island has thrown out a $388 million patent infringement jury verdict against Microsoft.
A jury in April found that Microsoft, the world's largest software maker, had infringed on a patent owned by Uniloc Inc.
Irvine, Calif.-based Uniloc makes software that prevents people from illegally installing software on multiple computers. Uniloc says Microsoft's Windows XP and some Office programs infringe on a related patent.
U.S. District Judge William Smith dismissed the verdict Tuesday and ruled in Microsoft's favor. He sides with Microsoft's objection to a pie chart Uniloc used at trial showing $19.27 billion as the total revenue from Windows XP and some office programs.
Microsoft, based in Redmond, Wash., says it is pleased. Lawyers for Uniloc did not immediately return a call seeking comment Wednesday.
